This game was my attempt to make a "memory game" that was more fun to play than most. I think I succeeded -- partly by the addition of some "bad" things you can match.
Match dynamite with a gem and it blows up all matching gem colors, keeping you from getting the highest score.
Match a skull and it swaps everything in two rows or two columns, making it harder to remember where things were.
I also spent some time "juicing up" the game with some good sound effects, particles, and animations.
